Abstract : Matrices to contain 150C phosphoric acid were perfected. These matrices contain an organic fibre, Kynol, and a thermo-setting binder of similar chemical structure, Resinox. In addition Ta2O5 is added to improve the wetting characteristics. The matrices can be produced in uniform, large sheets. Anodes for the oxidation of hydrogen contaminated with carbon monoxide in H3PO4 were also explored. Using supported catalyst techniques, CO tolerant anodes contain .8 mg/sq cm of a mixture of platinum and ruthenium performed at better than .6V at 100mA/sq cm current density for a period in excess of 500 hours.
